One off a 200 or 300 or disco 1 V8 will be a straight fit, manual or auto doesn't matter, the D2 ones can be fitted but will need some parts changing such as front drive flange, handbrake casting to get speedo drive and hi/lo lever, more if it doesn't have diff lock Dave

Cheers for that , thats just what i wanted to know, seen a few off autos but wasnt sure plus think id seen something on here that the auto ones should be in better shape due to the auto gear box , the transfer boxes ive seen on ebay average 130-150 but dont want to fit something thats going to last 5 minutes just because of the labour cost, get the impression you cant check much on them until fitted, theres a couple local for sale around 150 with gearbox approx 160000 on them?

Try the Ashcroft Transmission website. It has a ratio calculator. It will give you a guide on the different boxes and ratios depending on what outcome you want. 1995 Defender 110 CSW

Hi there, im after tge disco ratio, only really use it on road and want it re-chipping, i know its a defender but it is sloooow! something isnt right with it but money is getting stupid! Ive range rover whhels with allterrains on so speedos over reading by approx 10% , just fitted a rev counter and slickshift tonight not easy with a torch ha but havnt tried them out tonight, as per other posts rev counters on the slow side!
Need to get it on diagnostics as hits 50 easy enough but put foot to the floor and it sounds and feels like its revving its nuts off, cleaned all sensors, new fuel pump,injector harness,props,fuel filter,oils,air filter, wastgate, manual boost control with gauge,so apart from fuel pressure reg or replacing maff im stumped!

Unplug the maf and drive it for a couple of days, if the maf is dead some performance should come back pretty much straight away with it unplugged. Ray

Well i tried unplugging it and took it for a 5 minute blast but felt no different, ive done same procedure on my old merc and there was a big difference so felt no nearer to solving the problem, if i keep foot light and let speed build its pretty refined upto 60, but put foot down hard after 50 in 5th gear and you would think its going to blow!

Reading this it would look like you want to do the opposite to me.. I'm looking to raise the revs on mine due to larger wheels.. Anyhow you need to make sure that the replacement transfer box is 1.211:1 that will lower your revs, or give you a higher top end Wink

The standard ratio for the Defender is 1.410:1, going to a 1.211:1 box will drop your revs at 70 by appx 300 RPM.. it doesn't sound much, but it will make a big difference..

And make sure that the transfer has a locking diff... Later D2s did away with this in favour of traction control and run an open diff..

Just make sure it looks like this..
